7dp5dt / 14 days past trigger

Soo frustrated. I’m 7dp5dt and I’ve been testing out my trigger shot which I’m 14 days past. I’m still getting very noticible lines on Accumed test strips that seem to be the same color for the past three days and i just took a first response and it was no line. I had a faint positive on first response and now nothing. Are cheap test more sensitive then first response because now I’m just confused. Bottom is 7dp5dt
